I need to make my 6.0 alittle louder and faster. Where can i find these Tubi cat bypass tubes that ive heard about? Whats a good way to get more sound and performance out of the crappy muffler system on the 2001 6.0? If I hog out the cats will the fuel management still operate properly? Any insight is helpful, thanks

Go here and ask for Kurt----> www.ferraribooks.com

Thats where I ordered my pipes from.Do not hog out the stockers as they are expensive to replace when you sell your car.He can also get you a muffler delete piece that will make your car sound awesome,drop 100 pounds of weight,and pick up around 20 hp.

What do the pipes cost? And the muffler delete option? Have you done any other mods? I just ordered 2 K and N filters part number 33-2573 that are very similar to the stock size filters. They spec for a BMW for $33 a piece. I will let everyone know if I can make them fit.

You pick up much more than 20hp when you delete the cats!
